It's probably too late to warn you, but I smeared anhydrous lanolin on my prop last year (I keep my boat on a mooring in Buzzards Bay).
When I hauled at the end of the season, I had more barnacles than ever before. In previous years, I just polished the prop and waxed it several times; still had barnacles at the end of the season.
This year I tried something new: I scrubbed off the barnacles and some dark crud (perhaps the residue from the lanolin?).
Then I sprayed an Interlux zinc-based primer onto the prop (masking off the shaft and the zinc).
I followed that by three heavy coats of Interlux's antifouling for metal boats.
The antifouling is ablative, so I'm not too optimistic about the result. However, I couldn't bring myself to spring $200 for the PropSpeed kit, even though it would last me several years.
I'll try to remember to report on this at the end of the season.
